This profile is designed for printing with ColorFabb PLA/PHA 2.85mm filament on the Ultimaker S5 using curaSlicer. It is ideal for makers and engineers seeking to produce tough, biodegradable parts with reliable print quality and strong inter-layer adhesion. The settings are tuned to balance print strength, surface finish, and consistent results, making it suitable for a wide range of medium-sized projects.
The profile leverages a slightly elevated print temperature to accommodate the PHA blend in ColorFabb’s PLA/PHA filament, which enhances toughness and layer bonding. Standard layer heights and infill densities are chosen to provide a good mix of detail and strength, while cooling and speed settings are optimized for dependable extrusion and minimal warping. The use of a skirt for bed adhesion ensures clean starts without complicating removal.
Print Temperature: The nozzle is set to 215°C (220°C for the first layer) to ensure the PHA blend flows well and bonds layers tightly, resulting in tougher parts than standard PLA.
Layer Height: A standard 0.2mm layer height is used, balancing print speed and surface quality for most applications.
Infill Density and Pattern: The profile uses approximately 25% infill with a gyroid pattern, providing strength and even distribution of forces within the part.
Cooling: The part cooling fan is set to 80% after the initial layers, which helps solidify each layer quickly and reduces stringing or deformation.
Bed Adhesion: A skirt is used to prime the nozzle and ensure a clean start, minimizing the risk of warping or poor first layer adhesion.
Walls and Top/Bottom Layers: Two perimeter walls and five top/bottom layers are specified to enhance part strength and surface finish.
